Get classpath for gradle project using Android plugin

Question

I\'ve been building some tasks for a gradle multi-project build and have a need to get the class path for a project. The build script has projects that use the Java plugin

Answer 1

Here is another example a gradle task that generates javadocs with umlgraph + graphiz in an android project and includes classpath for all variants using the coding example given in the user1737310's previous answer. It is manually including android.jar from the selected runtime, I am still looking for a way to retrieve it dynamically.

    task javadoc(dependsOn: build) {
    setDescription('Generates Javadoc API documentation with UMLGraph diagrams')
    setGroup(JavaBasePlugin.DOCUMENTATION_GROUP)

    doLast {
        def javaFilePath = file('src/main/java')
        def cp = [System.getenv('ANDROID_HOME')+'/platforms/android-26/android.jar'];
        project.android.applicationVariants.all { v ->
            v.getCompileClasspath(null).getFiles().each{
                File f->
                    cp.add(f.getAbsolutePath())//this is the one of classpath
            }
        }
        def classpath = ":"+cp.join(':')
        if (javaFilePath.exists()) {
            ant.javadoc(classpath: (configurations.umljavadoc).asPath + classpath, 
                        sourcepath: file('src/main/java'), 
                        packagenames: '*',
                        destdir: "${docsDir}/javadoc",
                        private: 'false',
                        docletpath: configurations.umljavadoc.asPath) {
                doclet(name: 'org.umlgraph.doclet.UmlGraphDoc') {
                    param(name: '-inferrel')
                    param(name: '-inferdep')
                    param(name: '-qualify')
                    param(name: '-postfixpackage')
                    param(name: '-hide', value: 'java.*')
                    param(name: '-collpackages', value: 'java.util.*')
                    param(name: '-nodefontsize', value: '9')
                    param(name: '-nodefontpackagesize', value: '7')
                    param(name: '-link', value: 'http://java.sun.com/j2se/1.5.0/docs/guide/javadoc/doclet/spec')
                    param(name: '-link', value: 'http://java.sun.com/j2se/1.5/docs/api')
                }
            }
        }
    }
}
